THE ADVANCE OF MODEL OUTPUT STATISTICS METHOD IN CHINA

In 1972, Glahn and Lowry proposed a Model Output Statistics (MOS) method for weather forecasting. In 1978, Shanghai Meteorological Observatory recommended the MOS method. and used in operation. In 1979,Jilin Province using the Model Output from facsimile broadcast developed a regional MOS method. In 1982,State Meteorological Administration decided to develop the MOS method in broad meteorological obseratory or station and Jilin, Jiansu, Shanxi and Guangdong Provinces organized a research group for a regional MOS method. At the end of 1983,25 provinces are using the MOS method or PP method in China. The Regional MOS in China has distinctive feature. The factors of the regional MOS are not selected by screening the thousands of quantity but are depended on the fore-castor's experiences and the local weather researches. Many statistics models are used in the regional MOS. There are ten provinces using MOS or PP in extendeds range forecasting in China.
